Round barrel type solar hot water warmer

Abstract

Provided is a round barrel type solar hot water warmer. Sunlight penetrates through side arc transparent glass and top surface round transparent glass to irradiate on an endothermic film which is arranged on the surface of the surface of a round barrel-shaped heat absorption water tank, wherein the side arc transparent glass is arranged around the round barrel-shaped heat absorption water tank, and the top surface round transparent glass is arranged on the top surface of the round barrel-shaped heat absorption water tank. The temperature of water inside the gap between the heat absorption water tank and a round barrel-shaped water storage tank into the heat absorption water tank gradually rises. Heat inside the water is naturally radiated inside a heat accumulation water tank by the inner surface of the water storage tank and automatically circulates to the inside of the heat accumulation water tank through a heat circulating pump. When a faucet is opened or a delayed touch device is touched or a temperature controller which is used for producing heat is power-on, hot water inside the heat accumulation water tank flows out of the faucet naturally or the faucet immediately flows out the hot water or the temperature around a water pipe which is used for producing the heat rises. When the temperature inside a hot water output pipe is lower than 40 DEG C, a low-voltage direct current electric heater is heated and increases the temperature automatically, wherein the low-voltage direct current electric heater is supplied with a power source by a solar battery and a controller outputs a low-voltage direct current power source. Therefore, the water temperature is guaranteed to meet demands and the safety of low-voltage power utilization is guaranteed.

Description

technical field [0001] The invention relates to a drum type solar hot water heater, which is used for hot water production or heating and hot water production. Background technique [0002] At present, most of the existing technologies use solar vacuum tube water heaters. The vacuum tubes of this technology are easy to burst, and the carrying water pressure is low. The remaining hot water in the water tank is mixed with cold water after replenishment. The heat conduction speed of the layer pipe wall is too fast, the outer shell surface of the water tank insulation layer is directly in contact with the surrounding cold air, the surface temperature is low, and the heat emitted from the inside to the outside cannot be recovered at all, the heat preservation rate of the water tank is low, and the hot water heat preservation time is too short. The water temperature is too low in the cold season, and the water is cold for a while after turning on the tap. Contents of the inventi...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a drum-type solar hot water heater to solve the problem that the vacuum tube in the prior art is easy to burst, the bearing water pressure is low, and the remaining hot water in the water tank is supplemented. After the cold water is mixed, the water temperature drops sharply. The heat conduction speed is too fast through the outer wall of the glass vacuum tube, the outer shell surface of the water tank insulation layer is in direct contact with the surrounding cold air, the surface temperature is low, and the heat emitted from the inside to the outside cannot be recovered at all, and the heat preservation rate of the water tank is low. The water holding time is too short, the water temperature is too low in the cold season, the problem of cold water for a period of time after turning on the tap
